SIM PIN Programming - continued
How to Change the PIN Value Entered by the Automatic PIN Entry Feature
REMINDER: Automatic PIN entry must be disabled - before and while the automatic
PIN entry value is changed - until programming of the new PIN and Auto PIN Entry is
completed.
1) Using a tone-dial (DTMF) POTS telephone connected to the Phone port, lift up
the handset
(take off-hook) .
2) Enter the Programming mode:
Press: #
*
0
*
1 2 3 4 5 6 7 8 #
The dial tone will cease upon entry of the first digit. If you enter the access code
correctly, the dial tone should change to a different, steady “Programming” tone
and the bottom LED indicator on the front of the Phonecell will blink alternately
RED and GREEN to indicate that you’re in the programming mode.
3) Press: #
*
64
*
< old_PIN>
*
<new PIN>
*
<new PIN> #
The new SIM PIN will be supplied by the service provider with a new SIM.
If the SIM card is changed, the PIN must be reprogrammed using the above
command with the correct new PIN for the new SIM.
NOTE : The factory default PIN setting within the FWT’s non-volatile memory is
" 1234. "
4) Correct entry will be confirmed by the return of the programming tone, which
signifies that the unit is ready to accept the next entry. Incorrect entry will result in
a short, three tone sequence of rising frequencies, followed by the return of the
programming tone, which again signifies that the unit is ready to accept the
corrected entry.
5) Hang up the telephone handset (place on-hook).
For Example: To set up a new SIM with PIN "5678,"
dial: #
*
64
*
1 2 3 4
*
5 6 7 8
*
5 6 7 8 #
NOTE : This procedure will not change the PIN encoded on the SIM. It will only
change the PIN stored in the FWT for automatic entry of the PIN when requested
by the GSM module.
If the SIM card in use has SIM PIN Entry enabled, it is strongly recommended
that Automatic PIN Entry be selected.
IMPORTANT!
You must enter the PIN correctly. After three attempts to load an incorrect PIN, the
SIM will be blocked and the SIM card will have to be unblocked. If you do not
have the unblocking key, the SIM will have to be returned to the service provider
for reactivation.
